CHARLES A. LANGE, OF GASOONADE COUNTY, MISSOURI.

CABLE WATER-GATE.

SPECIFICATION forming part of Letters Patent No. 549,572, dated November 12, 1895.

Application filed April 4,1895. $eria1No.544,514. (No model.)

State of Missouri, have invented certain new and useful Improvements in Flood or Vater Gates, of which the following is a specification.

My invention relates to flood-gates, the objectbeing to improve this form of gate, whereby it may be surely and easily self-operative.

The drawing is a front view of a gate embodying my invention.

Referring to the drawing, P P are posts or uprights which are arranged opposite to each other at a suitable distance apart, and between which the gate is suspended.

At the upper end of the post or upright P there is a pulley WV, mounted upon an axle p, and preferably .inclosed by a bracket B, secured to the said post.

Occupying a corresponding position on the post or upright P there is an eye H.

G represents a gate, which may be of any suitable construction.

An upright frame consisting of the uprights A and the cross connecting-piece A is secured to the upper cross-bar of the gate at 19 In the upper ends of the uprights A are mounted the pulleys W, under which passes the rope R, by which the gate is suspended. One end of the rope is provided with a hook h, which is adapted to engage with the eye H, and at the opposite end of the rope there is supported the weight w. The rope extends from the eye H down to and under the pulleys W on the upright frame of the gate, and thence,'over the pulley IV, to the weight w.

It will be observed that the gate is thus free to move up and down and to swing either forward or backward; but as it is sometimes not desirable to permit the gate to swing in one direction, I use a suitable form of device for holding the same in a normal position, which device is shown in the drawing as being a bracing post or support I).

. The weight W has sufficient size nearly, but not quite, to counterbalance the gate, so that the gate normally occupies the position shown. in the drawing. Should, however, the

stream over which the gate is situated become swollen, the rising of the water will lift the gate, the weight at the same time falling. It will be understood that the lower portion of the gate rests in the water when the stream rises, and by reason of the gates being free to swing it permits the passage of drift. WVhen the water subsides, the gate returns to its normal position.

The construction of the parts by which the gate automatically rises and falls with the height of water is exceedingly simple and effective. It is advantageous over those constructions in which are employed two sets of weights and connecting devices, one for either side of the gate, as the use of the single weight, arranged as shown, besides being a simplification in arrangement, insures that a uniform lifting action shall-be applied to both sides of the gate simultaneously, so that it is practically impossible for one side to be raised higher than the other.

' Having thus described my invention, what I claim, and desire to secure byLetters Patent, is-

1. The combination in a flood gate, of the gate, the supporting posts one at either end of the gate, and a single rope secured at one end to one of the posts and passing thence under pulleys carried by the gate and over a pulley upon the opposite post, and a weight secured to the free end of the rope, substantially as set forth.

2. In combination with a gate and its sup porting posts,P, P ,the upright frame secured to the gate and consisting of the uprights, A, A, and a cross-piece, pulleys supported in the tops of said uprights, a rope support-ed upon the posts, P, P, and passing under the pulleys on the said upright frame, and a weight to counterbalance the gate secured to one end of said rope, substantially as set forth.

Dated this 28th day of March, 1895.
